In court challenges across the country, the Department of Justice has maintained that the executive order is “facially legitimate” and was issued in good faith. It has also denied that it was meant to target members of a religious group. Instead, the administration has argued the travel ban is a lawful exercise of the president’s authority, given to him by Congress, to exclude noncitizens from the country.
